Specification of Letters Patent.

Patented Bed. 15, 1908.

Application filed May 20, 1908. Serial No. 433,931.

I do hereby declare the followin to be a full,

clear, and exact description of t e same, ref erence being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to improvements in smoke pipes for stoves, furnaces, etc. and has for.1ts object to provide means whereby the: accumulation of soot and'dirt may be readily removed from the pipe without the necessity of taking the pipe apart.

To this end the invention consists in certain novel details of construction and combinations and arrangements of parts, all as will be now described and the particular features of novelty pointed out in the appended.

claims.

In the accompanying drawings, wherein is illustrated the preferred embodiment-of the invention, Figure 1 is a pers ective view of a pipe section with the cover fbr the opening n the pipe pushed back Fig. 2 is a cross section. Fig. 3 is a longitudinal sectional view. Fig. 4 is a bottom view. Fig. 5 'is a detail view of the implement forcleaning out the pipe.

Similar letters of reference in the several figures indicate the same parts.

, Referring to the drawings, the letter A indicates one of the horizontal sections of an ordinary stove pipe, having a'relatively long and narrow opening a in the top intermediate the ends. This opening is adapted to be closed by a suitable cover, and in the present instance consists of a slide B, provided with guides b, on opposite sides formed by bending inward the edge of the metal of the slide. This guide B 006 crates with a guide groove 0. formedalong t e opposite side ofthe 0 ening a, by bending outward the metal 0 the pipe constituting the side walls of the 0 ening, as clearly shown. in Fig. 2. The sli e or cover B is provided with a knob or handle 6 by means of whicliit' may be easily 0 erated. In order to preventthe removal of t e slide at each extreme of movement the slide is pro- Vided with a suitable sto in, the present instance constituted by t e shank b of the K knob 12 which extends through the cover B which strikes against the ends a of the opening A, and thus prevents further movement of the slide. Theend walls of the opening 'are strengthened to withstand the re eated blows of the stop b and this is pre erably done by turning back the metal of the pipe and interlocking it with the edge of a metal stay or strengthening piece 0. secured to the ipe at each end of the opening, as shown in 1g. 3. from the i e an opening is formed in the bottom of the pipe opposite the opening A. In the present instance this opening is circular and within it is secured a plate or disk C, having sectorshaped openings ctherein. Rotatably mounted u on the disk C is a second disk or plate 0, a so having sector shaped openings 0 therein. The openings in the two'disks are so arranged that they may be brought into registry, thus opening communication with the interior of the pipe, or the integral portion of the disk C may be brought over the openings 0 in disk C, to close communication, all as will be readily understood.

The im lement for removing the soot is illustrate in Fig. 5, and it consists preferably of a sheet-metal blade or head E, semicircular in shape, and to this blade is secured a flexible handle e of twisted wire, whereby the handle may bend to permit the implement to be used in the curves or elbows of 1 es. Y p rom the above description the invention will be readily understood.

When it is desired to clean out a pipe, the

slide or cover is pushed back to uncover the o ening in the pipe, the blade E inserted tlgrou h the opening being turned parallel with t e pipe to permit this, and then turned at right angles with the pi e. may then be worked within t e pipe and the dirt scraped out through the openings in the disks 0 and O. v

- Having thus described the invention, what is claimed as new, is:

- 1. In a stove pipe having a relatively long narrow opening intermediate its ends and having reinforced end walls, the combination with a cover for said opening, a handle car-' ried by said cover the shank of which extends through the cover constituting a stop, adapted to abut against the end walls of the open ing, whereby the movement of the cover in either direction will be arrested.

In order to remove the soot and dirt The blade 2. stove pipe provided with an opening 1 sure adapted to abut the end walls of the intermediate. 1ts' ends, stay pieces secured to opening to limit the movement of the closure the 1pipe at each end of the opening, the edge in each direction.
